Hopping parameter output

[GoogleCodeExporter]

QUEST has some non obvious way of printing hopping parameter value.

for the rectangular lattice with t = 1 and shape 4x24

it gives:

----
                       t_up :            1.000000
                       t_dn :            1.000000
----

For the rectangular lattice with t = 1 and shape 2x48 

it gives:

----
                       t_up :            2.000000    1.000000
                       t_dn :            2.000000    1.000000

----

I see logic in this output, but still it is not ok, at least because it is not 
obvious and because it costed me 2 hours of my life to figure this out.

I do not know what QUEST gives for Ehsan and his 1/5 depleted lattice but my 
guess that it is also something non obvious.

I am not clear what do you mean by ``logic'', and what is OK or not OK.

But there is an issue in your 2x48 example: by setting t=1 along the rung 
direction (L=2) direction, the hopping amplitude double counts. Hence the
t=2.0 result. Try t=0.5 in the rung direction instead, unless setting t=1 is
your intention.
